Organization is key!

Do you lose stuff in your bedroom? Have you spent countless hours looking for that lost sock or that missing piece of Ms. Johnson's homework? If so, then you need ORGANIZATION! Science is all about organization. Your Mastery Assessment is to create an an infomercial with the purpose of selling the periodic table to a group of very unorganized scientists.

What should you know?

1. What is an element? A: An element is a substance that is made entirely from one type of atom. http://education.jlab.org/qa/element.html
2. What are elements made of? A: the element hydrogen is made from atoms containing a single proton and a single electron. http://education.jlab.org/qa/element.html
3. How are elements different from each other? A: An atom is the smallest particle of any element that still retains the characteristics of that element. An element is made of many atoms and all atoms in one element are the same. http://www.ndt-ed.org/EducationResources/HighSchool/Radiography/atomselements.htm
   
4. How many different elements are there? A: 117 different types of elements http://education.jlab.org/qa/element.html
5. In terms of chemistry--what is a property? A: a characteristic of a sample of matter that is fixed by its state. http://chemistry.about.com/od/chemistryglossary/a/propertydef.htm
6. How are elements on the periodic table grouped? Why? metals and nonmetals because they are arrange according to there similar properties http://chemistry.about.com/library/weekly/blgroups.htm
7. What are the vertical columns and the horizontal rows called on the periodic table? What are their significance? A: Vertical are groups and horizontal are period.http://www.chemicool.com/
8. What are the features of the periodic table? (How do you read it?) A: The top number is the atomic number. Below the name is the element's atomic mass. The large letter is the element's symbol, and just below that is the element's name. When you look at the periodic table, you should notice that each box represents a different element, and each box contains vital information about the element, including its name, symbol, atomic number, and atomic mass. Look at the sample box below for a description of each of these pieces of information. http://web.buddyproject.org/web017/web017/pertab.html

Mastery Assessment

Deadline: 3/2/2010
Science Rocks, Inc. has hired you for a marketing assignment. You and your team have been tasked with creating an infomercial with the purpose of selling the periodic table to a group of unorganized scientists. They see nothing wrong with the way they keep their elements "organized" so you must point out every feature of the periodic table to prove to them they need this tool.
